Which process is used to determine whether a presented identity matches a known candidate among many possibilities?

• A. Verification
• B. Identification
• C. Watch list matching
• D. Group ID matching

Answer: (B)

Identifying someone among many possibilities is identification. In security and biometrics, identification is a one-to-many process: you compare the presented identity against a database of enrolled identities to see if there is a match and determine who the person is. This differs from verification, which is a one-to-one check that answers “are you who you claim to be?” by comparing the presented identity to a specific claimed identity. Watch list matching is a specialized form of identification against a predefined list, while Group ID matching isn’t a standard term for this process.
